Hello, 3D printing experts!
I have a quick question to the ones from knows about cooling, while printing with PLA filament.
My problem is that I got UM2 to work with, after some "experts" have been using it. And I am wondering how much cooling in needed for my prints, while i print out of PLA. For now, turns out, that both side fans are hardware-way turned OFF and it's only the middle fan, which is working, while it's is printing with PLA(i would say the quality is best).
Could you please clerify for me how much of a cooling is needed and does it differs from when i print the first layer or any other?
Sorry, got totally confused now... And since I am hardware reconnecting all the fans, could you please confirm which way they have to blow? Are they suppose to blow cool air towards the heater or they are supposed to take warm air from the heater and blow air away?
I am using Simplify3D as a slicer, so i could easily customize the fan speeds of any layer.
Thank you in advance.
Best regards,
Ilja
